LINE-SHAFT JOURNAL-BOX. r

To all whom it may concern:

Be itknown that I, FREDRIOK A. R013- ERTS, citizen of the United States, residing at Dickey, in the county of Lajmoure and State of North Dakota, have invented cer tain new and useful Improvements in Line- Shaft Journal-Boxes, of which the following is'a specification. Q

This inventionfrelates tojournal boxes and has as its primary aim toprovidea journal box particularly well adapted for use in connection with" line-shafts.

A further aim of the invention isto pro vide a line-shaft journal box whichmay be readilyassembled with the shaft to be journaled, without the necessity of dismounting the shaft. 1

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which 1-- Figure 1 is a top plan view of the journal box embodying the present invention, the cap of the box being removed. Fig. 2 is a vertical longitudinal sectional view on the line 2 2 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

In the drawings the box is illustrated as including a bottom 1, side walls 2, endwalls 3, and a cap or cover 4. The endwalls 3 are formed with recesses 5 which open at their upper edges, the bottom walls of these recesses being semi-cylindrical whereby to conform to the cross-sectional contour of the shaft to be journaled. The cap-plate 4 is formed or provided at its ends with depending fillers 6 which fit within the recesses 5 and these fillers at their lower ends are cut away as at 7 so as to conform to the cross-sectional contour of the upper side of the shaft. The opposite side walls 2 of the box are formed with vertically extending oppositely located grooves 8 in which are fitted the vertical edges of the division-plates 9. By referring to the draw ings, it will be observed that each of these division-plates is located in a plane parallel to and adjacent an end-wall 3 of the box. The division-plates 9 are recessed as at 10 in the same manner as are the end-walls of the box and they form, in conjunction with the said end-walls and the adjacent portions of the side walls, compartments in Specification of Letters Patent. PatentedSe pt. *7, 1915., Application filed September 25, 1912. Serial No. 722,354. J 1 V which the lubricant is containedli Arranged within the box between the divisionplates 9 is a pillow-block 11 havingits upp l lower s de of the shaft to be ournaled. .A' cap-plate 13 is disposed upon the. pillow.

per side channeled asflat 12 to receive the block and is formed in its under side with a channel 14 fitting the upper side of the said shaft, the shaft being indicated by the numeral 15. Thecap-plate13 is securedin place by means of suitablestud-bolts 16 which are fitted through the plate, through packing strips 17 arrangedbetween the under side ofthe plate and the upper side of. the pillow=block,-and threaded into the saidpillow-block.
